The Chargers running back did not practice all week, but as expected, he will play Sunday against the Broncos. A team source said Friday "that's the plan" when asked if Mathews would go, and indeed, he is active for a team that will be operating under a new-look offensive line.

Right guard Jeromey Clary (shoulder) won't go.

Left guard Johnnie Troutman moves to the starting lineup, left guard Chad Rinehart switching sides to take Clary's place.

San Diego used the same starting offensive line during its current five-game win streak. But Sunday's arrangement is the seventh different one this season. From left to right, it will go King Dunlap, Troutman, Nick Hardwick, Rinehart and D.J. Fluker.

Troutman, a 2012 fifth-round pick, missed his rookie season with a pre-draft pectoral injury. This is the 10th start of his career and first in the playoffs.
